Specification of Letters Patent.

Patented Nov. 2., 1915 Application filed June 4, 19M. Serial No.843,685. 7

To all whom it may concern j Be it known that I, SAMUEL J.;ALLLN, acitizen of the United States, residing at Kinmundy, in the county ofMarion and State of lllinois, haveinvented certain new and usefulImprovements in Snow-Flows; and I do declare the following to be a full,clear, and exact description of the invention, such as will'enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in snow plows and has for itsprimary object to provide a device of this character which may be used.to great advantage for the purpose of deflecting a body of snow to theright, to "the left or to both right and left, from a sidewalk or othersurface.

in carrying out the above end, I provide a. plow, a draft beam pivotedthereto to swing ina lateral plane, a lever pivoted to the plow andadapted to swing said beam, a rearwardly extending operating barattached at its forward end to said lever, and means controllable fromthe lever and from the rear end of said bar for locking the lever inadjusted position.

A secondary object of the invention is to provide simple and efficientmeans for releasing the locking meanseither from the lever or from therear end of said operatinghar.

A further object of the invention is to provide a flexible operatinglink between the lever and the draft beam, whereby move ment of the twoin intersecting planes, is allowed.

A still further object of the invention is to construct the leveroperating bar and the flexible link of a single metal bar.

Still other objects of the invention are to provide simple and efficientmeans for reliev ing the draft bar of unnecessary strain and toconstruct the entire device in a comparatively simple yet extremelyefficient manner.

With these objects in view, the invention resides in certain novelfeatures of construc tion and combination herein described and claimedand shown in the drawings wherein Figure 1 is a side elevation of a snowplow constructed in accordance with my invention; Fig. 2 is a top planview thereof, the draft device being swung to one side in dotted lines;Fig. 3 is a longitudinal sectional view; and d-iS a transverse sectiontaken along the plane of the line 4'. 4.- of Fig. 3.

in the accompanying drawings, 1 have shown my invention as comprisingan, A- shaped plow 1, the latterincluding a pair of forwardly convergingside members 2, a transverse connecting bar 3 near the rear ends of saidmembers 2, a centrally disposed longitudinal bar or member 4: which issecured between the forward ends of the members 2 and has its rear endrigidly secured to the cross bar As is usual with devices of thischaracter, the active surfaces of the members 2 are preferably providedwith metal wear plates.

Pivoted near the front portion of the plow -1 is a draft appliance inthe form of a pair of thills 5 which are connected at their rear ends bya transverse bar or block 6 while a second transverse bar 7 is disposedfor ward thereof. As clearly shown in the drawings, the rear cross bar 6is pivotally con nected as indicated at 8 to the central member 4, saidpivot being here shown in the form of a screw which passes through abracing plate 9 overlying the cross bar 6 through said bar and throughthe rear end of adraft bar 10, said rear end being internosed betweenthe under side of the block 6 and the member 4. The forward portion ofthe bar 10 inclines upwardly and forwardly and is rigidly secured at 11to the front cross bar 7, said bar terminating a suitable dis tanceforward of said last mentioned bar and constituting a pivotal supportfor a swingle tree 12. By the provision of the draft bar 10 it will beseen that the thills proper and their transverse bars are relieved ofunnecessary strain which latter is exerted directly upon the pivot 8.

In order that the thills 5 may be swung laterally either from theforward portion of the machine or from the rear end thereof, I providethe following means: An upright lever 13 is pivoted at its lower end toone side of a bifurcated seat standard or post 14, said bifurcated endstraddling the central member 45 and being secured in any suitablemanner to the opposite sides thereof. The lever 13 rises a suitabledistance and is provided with an L-shaped thumb lever 15 which, throughthe instrumentality of a link 16, is adapted to retract a dog or pawl 17from engagement with a segmental IIOO rack 18 which is rigidly securedupon the plow. It'will therefore be seen that the lever may be swungaround its plvot when the pawl 17 is retracted, thus allowing the thillsto be swung laterally through the instrumentality of a flexible link 19which is loosely through an' upright guide 22, the rear end of saidlever being formed wlth an operating handle 23 to which an L- shapedthumb lever 2a is pivoted, said thumb lever being adapted to retract thedog or pawl 17 when rocked around its pivot, this being allowed by theprovision of a cable or wire 25 which passes slidably through a numberof guides 26 on the bar 20 and through a guide 27 which is disposedadjacent the thumb lever 15 to which the oppositeend of said cable orwire is attached. Itwill therefore be seen that movement of either ofthe thumb levers 15 or 2 1 will retract the dog or pawl 17, thusallowing the lever 13 to be rocked around its pivot by a person ridingupon a seat 28, carried .by the standard 14, or by a person walking inrear of the machine.

It will. be further noted byreference to the drawings, that theflexibility of the link 19 is imparted thereto by giving the same aquarter turn as indicated at 29, thus allowing said link to yield bothvertically and, laterally as the lever 13 and the draft appliance movearound their pivots in inter- 'secting planes.

As before suggested, it becomes necessary at times for the operator towalk in rear of the machine, from which he may not only control therelation of the thills with the plow but may steer the latter to acertain extent by means of a central steering handle 30 which latter issecured to the'central member 4 at its forward end while itsintermediate portion is supported by a spacing block 31 which overliesthe upper edges of the slde members 1 and the rear cross Copies of thispatent may be obtained. for

bar 3, a fastening screw 32 passingthrough said handle and thespacmgblock and into said cross bar.

1 From the foregoing description taken in connection with theaccompanying drawings, it will be seen that the relation of the thillsto the plow may be varied, thus causing the latter to deflect the bodyof snow in any desired direction. 5

I have described my invention with considerable ininuteness and have setforth certain specific embodiments for carrying out the objects of theinvention. 1 wish it understood however, that I do not wish to belimitedto details of construction otherthan those amplified in the appendedclaims.

' Having thusdescribed my invention what I claim as new anddesire tosecure byLet- .ers Patent is 1. Means of the class ing a laterallyswinging member operable in one plane, a lever operable in an intersectingplane, and a comparatively resilient bar pivoted near one end to saidlever, said end being given aquarter turn and pivoted to the laterallyswinging member, the other end of said bar being disposed at a pointremote from the lever, whereby a supplebar connecting therear endsthereof, a front cross bar spaced inadvance of the rear bar,

neath the rear cross bar and its front end disposed aboveand extendedforwardly from the front cross bar, a pivot passlng described eomprisadraft bar having its rear end-disposed bethrough the rear cross bar andthrough the 7 rear end of the draft bar, means securing said draft barto the front cross bar, and a tree pivoted to the projecting front endof said draft bar.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
